142.6 divided by 2.3

Answer:

non-proportional

Step-by-step explanation:

This equation is non-proportional. A proportional equation contains 2 variables where one is proportional to the other. An example would be:

y = 5x

Y is proportional to the value of X at a rate of 5. 5 is the "constant of variation", or the "constant of proportionality"

36 = 12d is not proportional because there is only one variable. That variable can be solved for, giving only one solution.

proportional:

"corresponding in size, degree or intensity"

"having the same or a constant ratio"

The investment firm's total profit is $ 3360 and the percent profit for their total investment is 16.8%.

How to calculate percentage of a situation?
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it. There is no dimension to percentages. As a result, it is known as a dimensionless number. When we say a number is 50% of anything, we mean that it is 50% of everything.
Formula for percentages: (Value/Total value) * 100

Given, amount invested in company A = $ 12,000
Amount invested in company B = $ 8000
Profit earned by company A = 14%
Profit earned by company B = 21%
Amount in profit earned from company A = (12000*14)/100 = $ 1680
Amount in profit earned from company B = (8000*21)/100 = $ 1680
Therefore total profit of the investment firm = $ (1680 + 1680) = $ 3360
Thus, the investment firm's total profit is $ 3360.
Now, percentage profit of total investment = (3360/20000)*100 = 16.8%, using available literature and formula.
Thus, the percent profit for their total investment is 16.8%

In a school for every 5 male students there are 13 female students. If the total number of students is 34,000, how many men and women are there?

Answer:

14 years

Step-by-step explanation:

here;

A = P(1-r)^n

we want to cut the purchasing power by half. What this means is that we will be making the amount half of what it used to be

what we want to calculate here is the value of n that makes A = P/2

r = 4.8% = 4.8/100 = 0.048

P/2 = P(1-0.048)^n

take off p from both sides

0.5 = 0.952^n

Take the log of both sides

log 0.5 = log 0.952^n

log 0.5 = n log 0.952

n = log 0.5/log 0.952 = 14.01

Which means the number of years is 14

The minimum number of times Johnny needs to use to the wheelbarrow until the delivery truck is filled up to 70%, whereby the shape of the truck is a rectangular prism is about 41 times

A rectangular prism is a three dimensional geometric figure with three pairs of parallel facing sides, and perpendicular adjacent faces.

Whereby the wheelbarrow and the truck are rectangular prisms, we get;

The dimensions of the wheel barrow are;

2 feet by 3 feet by 1.5 feet

The dimensions of the truck are;

11 feet by 8 feet by 6 feet

The amount of soil John puts in the truck = 70% of the volume of the truck

Therefore;

The amount of soil John puts in the truck = 11 feet × 8 feet × 6 feet × 70%

11 feet × 8 feet × 6 feet × 70% = 528 ft³ × 70% = 369.6 ft³

The number of times to use the wheelbarrow, n, is therefore;

n = 369.6 ft³ ÷ (2 ft × 3 ft × 1.5 ft) ≈ 41.0

The minimum number of times Johnny needs to use the wheelbarrow until the delivery truck is 70% filled is therefore 41  = 41 times

So,the value of the 30th percentile of the given data will be =P30=4

The cumulative distribution function of a real-valued random variable X, or simply the distribution function of X, assessed at x, is the likelihood that X will have a value less than or equal to x in probability theory and statistics.

Using the Cumulative Distribution Function to Calculate Probabilities

F(x) is a cumulative distribution function that calculates the likelihood that the random variable X is smaller than or equal to x:

To get the cumulative probability that X is less than or equal to 1, multiply P(X=0) by P(X = 0) by (P=1):

First, we will determine the value of the cumulative probability P(X<=x):

x         f(x)       P(X<=x)

1       0.02          0.02

2       0.01          0.03

Explanation:

Refer to the y = mx+b form

The slopes are the only thing we focus on. For the equations y = 6x-1 and y = -6x-4, the slopes are 6 and -6 in that order.

The slopes are not equal, so the lines aren't parallel.

The slopes aren't opposite reciprocals of one another, so they aren't perpendicular either. An example of an opposite reciprocal pairing would be 6 and -1/6. Any pair of nonzero opposite reciprocal slopes always multiply to -1.

Therefore, the two lines are neither parallel nor perpendicular, they just intersect.

The solution to the equation  is  mathematically given as

m=-2

This is further explained below.

Generally, the equation is  mathematically given as

\(\frac{m}{m+4}+\frac{1}{4-m}=\frac{m^2}{m^2-16}\)

Where

The LCM of the denominators  are

m^2-16=(m+4)(m-4)

Hence

\((m+4)(m-4)\left(\frac{m}{m+4}+\frac{4}{4-m}\right)=(m+4)(m-4) \cdot \frac{m^2}{m^2-16} \\\)

m(m-4)-4(m+4)=m^2

3). 15/2 cups; 2 1/2 cup.

6). 2 cups; 2/3 cup.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

A unit rate of 3.

That means the quotient of the total amount of cups by the amount in a cup.

From the given choices;

1). 2 1/2 cups; 5/6 cups.

The unit rate = 5/2 x 6/5 = 3

2). 3 3/4 cups; 2 cup.

The unit rate = 15/4 x 1/2 = 15/8

The value of a, b, c and d are 25, 3, 14 and 7 such that the sum of all rows, columns and diagonals are 48.

Given to us a magic square in which the sum of all rows, columns and diagonals are same. Then, we have to complete the missing numbers i.e., a, b, c and d respectively.

Let's proceed to solve this magic square accordingly.

First let's calculate that what will be the sum of all rows, columns and diagonals.

From the figure of magic square one diagonal is completely filled from that we can easily calculate the sum of the diagonals.

Sum = 5+16+27 = 48

Then, we can find the value of a, b, c and d easily.

5+a+18 = 48

23+a = 48

a = 48-23

a = 25

Therefore, the value of a is 25.

29+16+b = 48

45+b = 48

b = 48-45

b = 3

Therefore, the value of b is 3.

Now, 5+29+c = 48

34+b = 48

c = 48-34

c = 14

Therefore, the value of c is 14.

Then, we have

c+d+27 = 48

14+d+27 = 48

41+d = 48

d = 48-41

d = 7

Therefore, the value of d is 7.

Hence, we have completed the magic square in which the sum of all rows, columns and diagonals are 48.

Therefore, the value of a, b, c and d are 25, 3, 14 and 7 respectively.

Answer:

Alisson

In November, Alisson was given $12.

Step-by-step explanation:

The normal amount given to Alisson each month = $x

If in November Alisson was given $9 more than thrice her usual amount of $x, it implies that she was usually given $3 ($9/3) per month because $9 is three times (thrice) than $3.

Therefore, Alisson's usual amount per month which is  $x = $3

This implies that in November she was given $12 ($3 + $9), which was thrice more.

To check the correctness of the above reasoning, we recall that $12 is more by $9 than $3, and $9 is thrice than the $3 given to Alisson per month.
